### Features:

- Designed with "Auto Seat Technology"®
- A low rated and fully guided spring allows for more consistent Set Pressures from pop to pop.
- Consistent Set Pressures allows for repeatable use without the need for excessive repairs or resetting.
- Open, Close, Seat and Seal™
- Fully guided disk for the proper alignment, opening and closing, and reseating of the valve.
- Mechanical Stop prevents wear on parts and controls valve lift.
- Pop Action relief allows the valve to go to full lift at Set Pressure. This helps with DOT regulated applications.
- Non-rising stems allowing valves to be installed in small areas.
